Package io.helidon.config

Class PropertiesConfigParser

java.lang.Object

io.helidon.config.PropertiesConfigParser

All Implemented Interfaces:

ConfigParser

public class PropertiesConfigParser
extends Object
implements ConfigParser

ConfigParser implementation that parses Java Properties content.

The parser implementation supports ServiceLoader, i.e. Config.Builder can automatically load and register PropertiesConfigParser instance, if not disabled. And of course it can be registered programmatically.

Weight of the PropertiesConfigParser to be used by Config.Builder, if loaded automatically as a service, is 90.0.

Method Details

supportedMediaTypes

public Set<MediaType> supportedMediaTypes()

Description copied from interface: ConfigParser

Returns set of supported media types by the parser.

Set of supported media types is used when config system looks for appropriate parser based on media type of content.

ParsableSource implementations can use MediaTypes to probe for media type of content to provide it to config system through ConfigParser.Content.Builder.mediaType(io.helidon.common.media.type.MediaType).

Specified by:

supportedMediaTypes in interface ConfigParser

Returns:

supported media types by the parser

parse

public ConfigNode.ObjectNode parse(ConfigParser.Content content)
                            throws ConfigParserException

Description copied from interface: ConfigParser

Parses a specified ConfigContent into a hierarchical configuration representation.

Never returns null.

Specified by:

parse in interface ConfigParser

Parameters:

content - a content to be parsed

Returns:

parsed hierarchical configuration representation

Throws:

ConfigParserException - in case of problem to parse configuration from the source
